I want to plot a graph with one logarithmic axis using matplotlib. Sample program: import matplotlib.pyplot as plt a = [pow(10, i) for i in range(10)] # exponential fig = plt.figure() ax = fig.add_subplot(2, 1, 1) line, = ax.plot(a, color='blue', lw=2) plt.show()
1 Ιαν 2021 · How to Plot Logarithmic Axes in Matplotlib? Last Updated : 21 Jan, 2021. Axes’ in all plots using Matplotlib are linear by default, yscale () and xscale () method of the matplotlib.pyplot library can be used to change the y-axis or x-axis scale to logarithmic respectively.
Make a plot with log scaling on both the x- and y-axis. Call signatures: loglog([x], y, [fmt], data=None, **kwargs) loglog([x], y, [fmt], [x2], y2, [fmt2], ..., **kwargs) This is just a thin wrapper around plot which additionally changes both the x-axis and the y-axis to log scaling.
In this example, we use plt.loglog () to create a plot with both x and y axes on a logarithmic scale. The np.logspace () function generates logarithmically spaced numbers, which is ideal for demonstrating how to plot logarithmic axes in Matplotlib.
Detailed examples of Log Plots including changing color, size, log axes, and more in Python.
11 Φεβ 2022 · Additionally, we will showcase how to plot figures with logarithmic axes using Python and matplotlib package and understand which method to use depending on whether you are using the Pyplot or Object-oriented interface.
Axis scales# By default Matplotlib displays data on the axis using a linear scale. Matplotlib also supports logarithmic scales, and other less common scales as well. Usually this can be done directly by using the set_xscale or set_yscale methods.
